Abstract:Bilateral vocal fold paralysis (BVFP) in adduction is characterised by inspiratory dyspnea, due to the paramedian position of the vocal folds with narrowing of the airway at the glottic level. The condition is often life threatening and therefore requires surgical intervention to prevent acute asphyxiation or pulmonary consequences of chronic airway obstruction. Aside from corticosteroid administration and intubation, which are only temporary measures, the standard approach for improving respiration is to perf… Show more
“…These methods commonly involve arytenoidectomy, chordotomy, and cordectomy which reshape the glottis by means of shifts of existing anatomical structures. 7 However, the disadvantage of these procedures is that the changes associated with these procedures are often permanent and irreversible. Other experimental procedures like artificial laryngeal pacing, 8 injections of botulinum toxin 9 into the cricothyroid muscle are being practiced; however, further research in this area is required.…”
Introduction: Bilateral vocal cord paralysis is a rare but dangerous condition which results in shortness of breath and poor quality of voice. Only patients with severe bilateral vocal cord immobility require surgical intervention. In the present study, we describe the procedure of combined endoscopic and external surgical approach for lateralization of vocal cord in bilateral abductor palsy.

“…It is part of the upper respiratory tract, a speech organ and a protective barrier for the lower respiratory tract against aspiration and choking on food. 1 Impaired morphology of the larynx or the mobility of the structures result in the impairment of at least one of the functions of the organ. Bilateral vocal fold paralysis (BVFP) is an example of a condition in which both airway hydrodynamics and phonation are affected.…”
Background. Computational fluid dynamics (CFD), a rapidly developing instrument with a number of practical applications, allows calculation and visualization of the changing parameters of airflow in the upper respiratory tract.
“…There are many surgical techniques for laryngeal airway enlargement in patients with bilateral vocal fold immobility (7,8). Reconstructive procedures should be the treatments of choice, while destructive procedures should be chosen only if the recovery of nerve function is no longer to be expected.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
